Tyler Goodlet 096d211ed2 Document `@tractor.stream` 2019-03-25 22:11:42 -04:00
Tyler Goodlet e51f84af90 Require explicit marking of non async gen streaming funcs
Add `@tractor.stream` which must be used to denote non async generator
streaming functions which use the `tractor.Context` API to push values.
This enforces a more explicit denotation as well as allows enforcing the
declaration of the `ctx` argument in definitions.

Tyler Goodlet 2aa6ffce60 Provide each task's cancel scope to every `Context`
This begins moving toward explicitly decorated "streaming functions"
instead of checking for a `ctx` arg in the signature.

- provide each context with its task's top level `trio.CancelScope`
  such that tasks can cancel themselves explictly if needed via calling
  `Context.cancel_scope()`
- make `Actor.cancel_task()` a private method (`_cancel_task()`) and
  handle remote rpc calls specially such that the caller does not need
  to provide the `chan` argument; non-primitive types can't be passed on
  the wire and we don't want the client actor be require knowledge of
  the channel instance the request is associated with. This also ties into
  how we're tracking tasks right now (`Actor._rpc_tasks` is keyed by the
  call id, a UUID, *plus* the channel).
- make `_do_handshake` a private actor method
- use UUID version 4

Tyler Goodlet faa1f373b5 Add subactor loglevel propagation test
Can't seem to get the `capfd` fixture to capture subprocess logging to
stderr even though the console report shows the log message as being
captured? Skipping the test on the forkserver method for now.

Tyler Goodlet 7014a07986 Add "spawn" start method support
Add full support for using the "spawn" process starting method as per:
https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods

Add a  `spawn_method` argument to `tractor.run()` for specifying the
desired method explicitly. By default use the "fastest" method available.
On *nix systems this is the original "forkserver" method.

This should be the solution to getting windows support!

Tyler Goodlet 616192d853 Don't use async gen functions for the stream API
As mentioned in prior commits there's currently a bug in Python that
make async gens **not** task safe. Since this is the core cause of almost
all recent problems, instead implement our own async iterator derivative of
`trio.abc.ReceiveChannel` by wrapping a `trio._channel.MemoryReceiveChannel`.
This fits more natively with the memory channel API in ``trio`` and adds
potentially more flexibility for possible bidirectional inter-actor streaming
in the future.

Huge thanks to @oremanj and of course @njsmith for guidance on this one!

Tyler Goodlet 41c202db68 Add a multi-task subscriber test
In combination with `.aclose()`-ing the async gen instance returned from
`Portal.run()` this demonstrates the python bug:
https://bugs.python.org/issue32526

I've commented out the line that triggers the bug for now since this
case provides motivation for adding our own `trio.abc.ReceiveMemoryChannel`
implementation to be used instead of async gens directly (returned from
`Portal.run()`) since the latter is **not** task safe.

Tyler Goodlet 61680b3729 Use a receive mem channel inside portals
For now stop `.aclose()`-ing all async gens on portal close since it can
cause hangs and other weird behaviour if another task operates on the
same instance.

See https://bugs.python.org/issue32526.
